Happn — the hyperlocal dating app that shows you people you’ve crossed paths with — is growing faster than ever.

The French-based mobile app said Tuesday it boasts 13 million registered users, up from 10 million just two months ago. That’s 1.5 million users per month in both January and February — up from a monthly clip of 1.2 million last fall.

CEO Didier Rappaport said he expects the momentum to continue this year.

“This was not just about Valentine’s Day or New Year’s resolutions,” Rappaport told The Post.

Happn’s growth is being driven by the popularity of its unique algorithm, which shows its users other singles who have come within about 800 feet of them in their daily travels, he said.

Happn is on track to register 20 million users by July and 30 million by the end of 2016, he said.

The accelerated growth is catching the attention of investors. Rappaport is in New York this week visiting top venture funds about a Series C investing round expected to close in July.

So far, Happn has raised $22 million from investors including Indinvest Partners, Raine Ventures and Fabrice Grinda.

Separately Tuesday, Happn said it has hired Serge Gojkovich — a former exec at all-male dating app Grindr — as its US marketing chief.

New York City is now Happn’s largest US market, with Grand Central Terminal, Herald Square and Union Square ranking among the top “crossed path” locations on the app.

The Big Apple’s Happn users have doubled in number over the past year, now accounting for 25 percent of the US total for the app.
